Ask her what she plans to do to make it "ALL OK".

"You want to make it all okay? Why now? For the longest amount of time you wanted to leave me and on top of that you've been having an affair. Did you think I would just sit here like a dumb ass and wait for you to come to your senses? You disrespect me & my life so much that you think I would just wait like an idiot till you were done having sex with the other man? What do you plan on doing to make things ALL OK? Starting tonight what is the first thing you're going to do to show me you're going to make things all OK?"
